摘要 本文主要利用H(t,s)型函数和广义Riccati变换技巧,建立二阶中立型时滞拟线性微分方程[r(t)|x'(t)|γ-1x'(t)]'+q0(t)|y(t-σ)|γ-1y(t-σ)+q1(t)|y(t-σ1)|α-1y(t-σ1)+q2(t)|y(t-σ2)|β-1y(t-σ2)=0.其中x(t)=y(t)+p(t)y(t-τ),在0≤p(t)≤1的新的振动准则. Using H( t,s) type function and the generalized Riccati transformation technique,this thesis intended to establish the new oscillation criteria in 0≤p( t) ≤1 for a class of second- order neutral delay quasi- linear differential equations of the form[r( t) | x'( t) |^γ- 1x'( t) ]' + q0( t) | y( t- σ) |^γ- 1y( t- σ) + q1( t) | y( t- σ1) |^α- 1y( t- σ1) + q2( t) | y( t- σ2) |^β- 1y( t- σ2) = 0,x( t) = y( t) + p( t) y( t- τ).
